Description

Technical Field

[0001] The invention relates to a connecting structure of a door exterior molding installed at the waist of a vehicle door and a base component of a door rearview mirror. Background Art

[0002] A door exterior molding (hereinafter referred to as a molding) is installed along the door waistline near the outer waist of the vehicle, such as the front door. The molding guides the lifting switch of the door glass, and has the function of wiping off water droplets and dust from rain, car wash water, etc. attached to the door glass. It also has the function of improving the appearance quality as a part of the appearance design of the front door.

[0003] As a mounting structure of the molding, the structure described in the following patent document 1 is known. Fig.11 As shown, the molding 1 is an extruded product of a synthetic resin material in which a metal inlay plate 2 is embedded, and has an inverted U-shaped base 3, and sealing lips 4 and 5 which are arranged in upper and lower sections on the inner surface of the inner side wall 3a of the base 3 and abut against the outer surface of the door glass G. The base 3 is installed on the mounting flange 9 via a clamp 6 made of synthetic resin, and the mounting flange 9 is formed by joining the outer panel 7 of the automobile door and the reinforcement 8 parallel to the door glass G.

[0004] The clip 6 is pre-buried in the base 3 , and when the molding 1 is mounted on the mounting flange 9 in this state, the locking protrusion 6 a protruding from the clip 6 is fitted into the fitting hole 9 a of the mounting flange 9 , so that the molding 1 is mounted on the mounting flange 9 .

[0005] In addition, as another mounting structure, as described in Patent Document 2, for example, there is a structure in which, instead of using a clamp, the molding is fitted in a manner covering the upper edge of the door outer panel, and the end piece provided at the end of the molding and the lower end of the door frame are fixedly mounted using a screw clamp.

[0006] On the other hand, a door mirror is arranged at a position in front of the vehicle body of the front door. The door mirror has a base member fixed to the door panel, and one end of the molding in the longitudinal direction of the vehicle body front side is arranged opposite to the base member.

[0010] Patent Document 2: Japanese Patent No. 3412490 Summary of the invention

[0011] Problems to be solved by the invention

[0012] However, various mounting structures of moldings in the past are structures for mounting the moldings relative to the door panel or the door frame, and no consideration is given to the connection structure between one end portion of the molding in the length direction and the door mirror.

[0013] Therefore, when the above-mentioned conventional molding installation structure is used as it is, there is a risk that a gap will be generated between one end of the molding and the base member of the door rearview mirror opposite to the one end, or one end of the molding will be inserted into the inner side of the base member of the door rearview mirror to generate a step difference.

[0014] In this way, when a gap or a step is generated between one end portion of the molding and the base member of the door mirror, there is a risk that the sense of unity between the two is impaired and the aesthetics is deteriorated, resulting in a reduction in the quality of the appearance.

[0015] The present invention is proposed in view of the technical problems of the installation structure of the previous molding as mentioned above, and its purpose is to provide a connection structure between a door exterior molding and a door rearview mirror, which can suppress the generation of a gap or step difference between the two by connecting one end of the molding to the base component of the door rearview mirror via a connecting pin.

[0016] Means of solving problems

[0017] The invention described in claim 1 of the present application is a connecting structure that connects one end portion in the length direction of a door exterior molding installed at the waist of a vehicle door to a base member of a door mirror via a connecting pin, and is characterized in that:

[0018] The door exterior molding has a first insertion hole into which one end of the connecting pin in the longitudinal direction can be inserted, and a first locking hole is formed on a peripheral wall constituting the first insertion hole.

[0019] The base member has a second insertion hole into which the other end of the connecting pin in the longitudinal direction can be inserted, and a second locking hole is formed on a peripheral wall constituting the second insertion hole.

[0020] The connecting pin is provided with a first locking portion at one end in the length direction, and a second locking portion is provided at the other end in the length direction. When the one end is inserted into the first insertion hole, the first locking portion is locked with the hole edge of the first locking hole and can be elastically deformed in the inward and outward directions. When the other end is inserted into the second insertion hole, the second locking portion is locked with the hole edge of the second locking hole and can be elastically deformed in the inward and outward directions.

[0021] Effects of the Invention

[0022] According to the invention described in claim 1 of the present application, by connecting one end of the molding in the longitudinal direction to the base member of the door mirror using a connecting pin, a gap or step difference between the two is suppressed, a sense of unity is obtained, and the aesthetics is improved, thereby improving the appearance quality.

[0034] Hereinafter, an embodiment of a connection structure between a door exterior molding and a door mirror according to the present invention will be described based on the drawings.

[0035] Figure 1 The invention is a perspective view of the left side of the door mirror side of a vehicle to which the connection structure between the door exterior molding and the door mirror of the present invention is applied. Figure 2 1 is a perspective view showing a state in which one end of a door exterior molding and an end of a base portion of a door mirror are connected by a connecting pin in this embodiment. Figure 3 is a perspective view showing a state before one end portion of the connecting pin provided in the present embodiment is inserted into the first insertion hole of the molding, Figure 4 is a perspective view showing a state in which one end of a connecting pin provided in the present embodiment is inserted into a first insertion hole of a molding before the other end of the connecting pin is inserted into a second insertion hole of a base member of a door mirror. Figure 5 yes Figure 4 AA line section view.

[0036] like Figure 1 As shown, a door exterior molding (hereinafter referred to as molding) 11 is arranged along the front-rear direction of the vehicle body at the waist of a door body 10a of a front door 10 of the vehicle, and a door rearview mirror 12 is arranged at the front end of the door body 10a.

[0037] like Figure 5 As shown, the molding 11 is an extruded product of a synthetic resin material with a metal inlay plate 11b embedded inside, and has a base 13 with a cross-section that is roughly in the shape of an inverted U, sealing lips 14 and 15 that are arranged in upper and lower sections on the inner surface of the inner wall 13a of the base 13 and abut against the outer surface of the vehicle door glass outside the figure, and a metal-plated molded portion 16 that is embedded and fixed to the outer side of the base 13.

[0038] like Figure 3 to Figure 5 As shown, the base 13 forms a first insertion hole 17 along the longitudinal direction in the internal axial direction. The first insertion hole 17 is inserted into one end 22a of the connecting pin 22 to be described later, and has a cross-sectional inverted U-shaped shape similar to the cross-sectional shape of the one end 22a, and extends to the rear of the vehicle. In addition, the inner side wall 13a is provided with an abutting portion 13c at the lower end portion thereof to abut against the outer surface of the reinforcement member outside the drawing, and a supporting portion 13d is protrudingly provided at the approximately central position in the vertical direction of the inner surface to support the lower end surface of a side wall 24 of the connecting pin 22.

[0039] The length of the outer wall 13b of the base 13 in the vertical direction is formed shorter than that of the inner wall 13a, and the bent parts 16a and 16b provided at the upper and lower ends of the molded part 16 are embedded and fixed in the first and second fitting grooves 13e and 13f formed at the upper and lower ends along the longitudinal direction.

[0040] In addition, a first locking hole 18 is formed radially through the inner wall 13a at a position above the support portion 13d, and a first locking portion 26 included in an end portion 22a in the longitudinal direction of a connecting pin 22 to be described later is locked in the first locking hole 18.

[0041] like Figure 3 and Figure 4 As shown, the first locking hole 18 is provided at a predetermined position corresponding to the first locking portion 26 of the one end 22a of the connecting pin 22 inserted through the first insertion hole 17 from the one end 11a side in the longitudinal direction of the molding 11. The first locking hole 18 is formed in a rectangular shape long in the longitudinal direction, and has a linear first hole edge portion 18a on the inner end side and a linear second hole edge portion 18b on the outer end side opposite to each other in the longitudinal direction.

[0042] In addition, the molding 11, the base 13 of one end portion 11a other than the door mirror 12 side is mounted to a mounting flange by a mounting member such as a clamp or bolt, and the mounting flange is formed by joining the outer panel of the door body 10a of the front door 10 and a reinforcement member outside the drawing parallel to the door glass.

[0043] like Figure 1 , Figure 2 As shown, the door mirror 12 includes a base member 19 fixed to the front end portion of the front door 10 by bolts or the like not shown in the drawings, and a mirror body 12 a supported by the base member 19 .

[0044] like Figure 4As shown, the base member 19 is formed of a synthetic resin material into a special-shaped integral body, and a second insertion hole 20 is formed in the one end 11a of the molding 11 from the inside of the end 19a that is axially butted toward the front of the vehicle body. The second insertion hole 20 is inserted from the axial direction by the other end 22b of the connecting pin 22 to be described later, and is formed into an inverted U-shape similar to the cross-sectional shape of the other end 22b of the connecting pin 22. In addition, as shown in FIG. Figure 4 As shown, the width L1 of the second insertion hole 20 is formed to be larger than the width L of the first insertion hole 17 (see Figure 3 )Small.

[0045] Furthermore, a second locking hole 21 is formed through the side wall portion 19 b constituting the second insertion hole 20 of the base member 19 in the radial direction, and a second locking portion 27 included in the other end portion 22 b of the connecting pin 22 is locked in the second locking hole 21 .

[0046] like Figure 4 As shown, the second locking hole 21 is provided at a predetermined position corresponding to the second locking portion 27 of the other end portion 22b of the connecting pin 22 of the second insertion hole 20 on the same surface as the first locking hole 18. The second locking hole 21 is formed into a rectangular shape long in the length direction, and has a straight first hole edge portion 21a on the inner end side and a straight second hole edge portion 21b on the outer end side (see Figure 7 , Figure 8 ).

[0047] The connecting pin 22 is inserted into the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19 of the door mirror 12 .

[0048] Figure 6 1 and 2 show a connecting pin provided in the present embodiment, wherein (a) is a bird's-eye view of the connecting pin, (b) is a left side view of the connecting pin, and (c) is a top view of the connecting pin. Figure 7 1 is a longitudinal sectional view showing a state in which one end of a molding is connected to an end of a base member of a door mirror by a connecting pin provided in the present embodiment. Figure 8 yes Figure 7 , (a) is an enlarged longitudinal sectional view showing a state in which one end of a molding is connected to an end of a base member of a door mirror by a connecting pin provided in the present embodiment, (b) is an enlarged view of portion B of (a), and (c) is an enlarged view of portion C of (a).

[0049] like Figure 6As shown in (a) to (c), the connecting pin 22 is formed of a synthetic resin material to have an inverted U-shaped cross-section and has a specified length along the longitudinal direction. One end 22a in the longitudinal direction is inserted into the first insertion hole 17, and the other end 22b is inserted into the second insertion hole 22, respectively, approximately half of the longitudinal direction is configured.

[0050] In addition, the connecting pin 22 has an arc-shaped top 23 and two side walls 24 and 25 extending downward in parallel from both end edges of the top 23, and the side wall 24 on the vehicle outer side is formed to extend downward longer than the other side wall 25 on the vehicle inner side. The width W between the two outer surfaces of the two side walls 24 and 25 is set to be substantially the same as or slightly larger than the width L1 of the second insertion hole 20, and when the other end 22b is inserted into the second insertion hole 20, the entire outer surface of the other end 22b is inserted with a slight sliding contact resistance with the inner surface of the second insertion hole 20.

[0051] The first locking portion 26 and the second locking portion 27 are provided on the outer surface of the one end 22a side and the other end 22b side of the connecting pin 22 on the one side wall 24. The first locking portion 26 and the second locking portion 27 are provided in the form of being cut and raised from each opening portion 24a, 24b formed in the one side wall 24, forming an inclined shape in which each front end portion 26b, 27b side rises from each base end portion 26a, 27a toward the outside of the vehicle, and each front end portion 26b, 27b is arranged in directions opposite to each other. That is, each base end portion 26a, 27a is arranged in opposite directions to each other, and each front end portion 26b, 27b extending from each base end portion 26a, 27a is arranged opposite to each other. In addition, the first and second locking portions 26 and 27 are formed with the base end portions 26a and 27a as fulcrums, and the front end portions 26b and 27b can be elastically deformed in the vehicle interior and exterior directions (radial directions). When elastically deformed inward, they are completely accommodated in the opening portions 24a and 25a. When elastically deformed outward, the front end portions 26b and 27b protrude outward from the opening portions 24a and 25a.

[0052] Each front end portion 26b, 27b is formed with a thick cross-sectional thickness, and claws 26d, 27d are protrudingly provided at the inner edge of the first and second front end surfaces 26c, 27c, respectively, and each front end surface 26c, 27c is formed to be inclined upward from each outer edge to each claw 26d, 27d. That is, each front end surface 26c, 27c is not flat, but is formed to be inclined upward at a predetermined angle from each outer edge of each outer surface side to each claw 26d, 27d relative to the outer surface of each locking portion 26, 27. When each locking portion 26, 27 is locked to each first hole edge portion 18a, 21a of each locking hole 18, 21, each claw portion 26d, 27d is locked to the lower end edge of the corner edge 18c, 21c of each hole edge portion 18a, 21a, limiting the elastic deformation movement of each front end portion 26b, 27b toward each locking hole 18, 21.

[0053] And, if Figure 8 As shown in (a), the spacing distance T between the first hole edges 18a, 21a on the inner end sides of the first locking hole 18 and the second locking hole 21 is set to such a length: this length allows the two end portions 22a, 22b of the connecting pin 22 to be inserted into the respective insertion holes 17, 20, and the front end surfaces 26c, 27c of the front end portions 26b, 27b of the first locking portion 26 and the second locking portion 27 to be locked to the corner edges 18c, 21c of the first and second hole edges 18a, 21a of the first and second locking holes 18, 21.

[0054] Furthermore, if Figure 6 As shown, the connecting pin 22 is provided with a protrusion 28 at a position corresponding to the first locking portion 26 on the outer surface of the other side wall 25. Since the width L of the first insertion hole 17 is larger than the width L1 of the second insertion hole 20, the protrusion 28 is formed to fill the width difference. The protrusion 28 is formed in a long and narrow block shape along the length direction of the connecting pin 22. When the end 22a of the connecting pin 22 is inserted into the first insertion hole 17, the flat upper end surface 28a abuts against the inner surface of the outer side wall 13b of the base 13 constituting the first insertion hole 17, thereby preventing the elastic reaction force of the first locking portion 26 to the outside (toward the first locking hole 18) from being reduced. In addition, the front end surface 28b of the protrusion 28 is formed in an inclined surface shape, which plays a guiding function when the end 22a of the connecting pin 22 is inserted into the first insertion hole 17.

[0055] [Effects of this embodiment]

[0056] Next, the effects of the connection structure between the molding and the door mirror in the present embodiment will be described.

[0057] First, if Figure 3As shown, the end portion 22a of the connecting pin 22 is inserted into the first insertion hole 17 of the end portion 22a of the molding 11 from the direction of the arrow. In this way, for the connecting pin 22, the inclined front end surface 28b of the protrusion 28 slides in contact with one hole edge of the first insertion hole 17 while guiding the end portion 22a into the first insertion hole 17, and the upper end surface 28a slides in contact with the inner surface of the first insertion hole 17, that is, the inner surface of the outer wall 13b of the base 13, while guiding it inward. At this time, for the first locking portion 26, the first front end portion 26b slides in contact with the inner surface of one side wall of the first insertion hole 17 while elastically deforming inward, and the first front end portion 26b side is completely accommodated in the first opening 14a and moves inside.

[0058] And, if Figure 8 As shown in (a) and (b), when the first locking portion 26 reaches the position of the first locking hole 18, the first front end portion 26b elastically deforms outwards by its own restoring elastic restoring force and enters the first locking hole 18, and the inclined first front end face 26c of the first front end portion 26b elastically locks with the corner edge 18c of the first hole edge portion 18a in a line contact state. At this time, the claw portion 26d abuts against the lower end edge of the corner edge 18c of the first hole edge portion 18a, limiting the first front end portion 26b from further elastically deforming outwards.

[0059] Afterwards, if Figure 4 As shown in FIG. 1 , with one end 22a of the connecting pin 22 locked and fixed in the first insertion hole 17 of the molding 11, the other end 22b of the connecting pin 22 is inserted into the second insertion hole 20 of the base member 19 of the door mirror 12. In this way, the second locking portion 27 has the same function as the first locking portion 26, and the second front end 27b is elastically deformed inwardly and moved while being accommodated in the second opening 25a. And, when the second locking portion 27 reaches the second locking hole 21, as shown in FIG. Figure 8 As shown in (a) and (c), the second front end portion 27b elastically deforms outwards by its own elastic restoring force and enters the second locking hole 21, and the inclined second front end face 27c of the second front end portion 27b elastically locks with the corner edge 21c of the first hole edge portion 21a in a line contact state. At this time, the claw portion 27d elastically contacts with the corner edge 21c of the first hole edge portion 21a, limiting the second front end portion 27b from further elastically deforming outwards.

[0060] Thus, the one end portion 22 a of the molding 11 is firmly connected to the end portion 19 a of the base member 19 of the door mirror 12 via the connecting pin 22 .

[0061] In particular, in this embodiment, as described above, one end 22a and the other end 22b of the connecting pin 22 are respectively inserted into the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19, and the inclined first front end face 26c of the first locking portion 26 and the inclined second front end face 27c of the second locking portion 27 are locked to the corner edge 18c of the first hole edge portion 18a of the corresponding first locking hole 18 and the corner edge 21c of the first hole edge portion 21a of the second locking hole 21.

[0062] Thus, the fillet 11 and the base member 19, as Figure 8 As shown by the arrows in (b) and (c), the elastic force of the first locking portion 26 and the second locking portion 27 of the connecting pin 22 is applied in the direction of approaching each other. Figure 8 As shown in (b), when the inclined first front end surface 26c of the first locking portion 26 elastically contacts the corner edge 18c of the first hole edge portion 18a of the first locking hole 18 from obliquely below, the elastic force is as shown in the figure. Figure 8 As shown by the arrow in (b), the force acts to bias the molding 11 toward the end 19a of the base member 19. Figure 8 As shown in (c), when the inclined second front end surface 27c of the second locking portion 27 elastically contacts the corner edge 21c of the first hole edge portion 21a of the second locking hole 21 from obliquely below, the elastic force is as follows: Figure 8 As shown by the arrow in (c), the base member 19 is urged toward the direction of the one end portion 22a of the molding 11.

[0063] In this way, when the inclined first front end face 26c of the first locking portion 26 and the inclined second front end face 27c of the second locking portion 27 are elastically in contact with the respective corner edges 18c, 21c of the respective hole edge portions 18a, 21a of the corresponding first and second locking holes 18, 21 in a line contact state, with the help of the elastic reaction force of each locking portion 26, 27 in the direction opposite to the radial direction outward, one end portion 11a of the molding 11 and the end portion 19a of the base member 19 of the door rearview mirror 12 are forced in the direction of approaching each other, that is, in the direction of mutual attraction.

[0064] Therefore, if Figure 2 , Figure 7 and Figure 8 As shown in (a), one end portion 22a of the molding 11 is in close contact with the end portion 19a of the base member 19 of the door mirror 12, thereby fully suppressing the generation of a gap or step difference as in the prior art described in the aforementioned gazette, thereby improving the sense of unity and aesthetics, and seeking to improve the appearance quality.

[0065] In addition, in the present embodiment, since the first and second front end surfaces 26c and 27c of the first and second locking portions 26 and 27 are formed in an inclined shape, it is not necessary to increase the distance T between the two first hole edges 18a and 21a of the two locking holes 18 and 21 and the distance T1 between the front end surfaces 26c and 27c of the locking portions 26 and 27 (see Figure 6 (c)) relative dimensional accuracy. That is, since the inclined front end faces 26c and 27c absorb the deviation between the distance T and the distance T1, it is not necessary to improve the relative dimensional accuracy. Thus, the manufacturing operation becomes easier, thereby seeking to reduce the manufacturing cost.

[0066] [Second Implementation Method]

[0067] Fig. 9 (a) shows a second embodiment of the present invention. The structure of the second locking portion 27 of the connecting pin 22 is the same as that of the first embodiment, but the structure of the first front end portion 26b of the first locking portion 26 is changed.

[0068] That is, Fig. 9 As shown in (c), for the second locking portion 27 of the connecting pin 22, the second front end face 27c of the second front end portion 27b is formed into an inclined surface in the same manner as in the first embodiment, and the second front end face 27c elastically contacts the corner edge 21c of the first hole edge portion 21a of the second locking hole 21.

[0069] On the other hand, for the first locking portion 26, Fig. 9 As shown in (b), the first front end face 26c of the first front end portion 26b is not formed in an inclined shape, but is formed in a flat shape. That is, the first front end face 26c is formed in a flat shape that is substantially perpendicular to the outer surface of the first front end portion 26b. Therefore, when the first locking portion 26 is locked in the first locking hole 18, the first front end face 26c does not abut against the corner edge 18c of the first hole edge portion 18a, but abuts against the flat surface 18d extending inward from the corner edge 18c in a surface contact state from the axial direction.

[0070] Thus, in the present embodiment, when the first locking portion 26 and the second locking portion 27 of the connecting pin 22 are locked with the corresponding first locking hole 18 and the second locking hole 21, the first front end face 26c of the first locking portion 26 abuts against the flat surface 18d of the first locking hole 18 in a surface contact state from the axial direction, and on the other hand, the inclined second front end face 27c of the second locking portion 27 is elastically contacted and locked with the corner edge 21c of the first hole edge portion 21a in a line contact state, and therefore, in particular, the elastic force of the second locking portion 27 applies force in a direction in which the base member 19 and the molding 11 approach each other.

[0071] Therefore, in the second embodiment, as in the first embodiment, the one end 22a of the molding 11 is in close contact with the end 19a of the base member 19 of the door mirror 12, so that the integrated appearance is improved and the appearance quality is improved.

[0072] In addition, since the second front end surface 27c of the second locking portion 27 is formed in an inclined shape, even if the first front end surface 26c of the first locking portion 26 is flat, it is not necessary to improve the relative dimensional accuracy of the distance T between the two locking holes 18 and 21 and the distance between the front end surfaces 26c and 27c of the locking portions 26 and 27, as in the first embodiment. Thus, the manufacturing operation becomes easy, and the manufacturing cost is reduced.

[0073] [Third Implementation Method]

[0074] Fig.10 (a) shows a third embodiment of the present invention. The structure of the first front end portion 26b of the first locking portion 26 of the connecting pin 22 is the same as that of the second embodiment, but the structure of the second front end portion 27b of the second locking portion 27 is changed.

[0075] That is, for the first locking portion 26, Fig.10 As shown in (b), the first front end face 26c of the first front end portion 26b is formed to be flat in the same manner as in the second embodiment, and the first front end face 26c abuts against a flat surface 18d extending inward from the corner edge 18c of the first hole edge portion 18a of the first locking hole 18.

[0076] On the other hand, for the second locking portion 27, Fig.10 As shown in (c), the second front end face 27c of the second front end portion 27b is not inclined, but is formed flat like the first front end face 26c. Therefore, when the second locking portion 27 is locked in the second locking hole 21, the second front end face 27c does not abut against the corner edge 21c of the first hole edge portion 21a, but abuts against the flat surface 21d in a surface contact state from the axial direction.

[0077] Thus, in this embodiment, when the first locking portion 26 and the second locking portion 27 of the connecting pin 22 are locked with the corresponding first locking hole 18 and the second locking hole 21, the front end surfaces 26c and 27c of each locking portion 26 and 27 abut against the flat surfaces 18d and 21c of each locking hole 18 and 21 in a surface contact state from the axial direction.

[0078] Therefore, as in the first and second embodiments, without applying a large force in the direction of approaching the base member 19 and the molding 11, the one end 22a of the molding 11 can be brought into close contact with the end 19a of the base member 19 of the door mirror 12 by adopting a relatively high relative dimensional accuracy of the distance T between the two locking holes 18 and 21 and the distance between the front end surfaces 26c and 27c of the locking portions 26 and 27. As a result, the sense of unity and the aesthetics are improved, thereby improving the appearance quality.

[0079] The present invention is not limited to the structures of the above-described embodiments. For example, the structure of the connecting pin 22 may be changed according to the size or change of the cross-sectional shape of the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19 of the door mirror 12. In addition, the structures of the locking portions 26 and 27 may be arbitrarily changed according to the structural changes of the locking holes 18 and 21.
